In the case of polymer sustained vertical alignment (PSVA) and polyimide-less (PI-less) alignment technologies, polymer-alignment layers are formed by exposure of ultraviolet (UV) light to a liquid crystal (LC) layer including a LC composition and a reactive monomer. We were able to develop a high reliable fluorinated diluter for the LC composition toward the PSVA and the PI-less technologies. In addition, we also developed the PSVA and the PI-less in-plane switching mode LC cells with both
